Aims Patient-performed lung ultrasound (LUS) in a heart failure (HF) telemedicine model may be used to monitor worsening pulmonary oedema and to titrate therapy, potentially reducing HF admission. The aim of the study was to assess the feasibility of training HF patients to perform a LUS self-exam in a telemedicine model. Methods and results A pilot study was conducted at a public hospital involving subjects with a history of HF. After a 15 min training session involving a tutorial video, subjects performed a four-zone LUS using a handheld ultrasound. Exams were saved on a remote server and independently reviewed by two LUS experts. Studies were determined interpretable according to a strict definition: the presence of an intercostal space, and the presence of A-lines, B-lines, or both. Subjects also answered a questionnaire to gather feedback and assess self-efficacy. The median age of 44 subjects was 53 years (range, 36-64). Thirty (68%) were male. Last educational level attained was high school or below for 31 subjects (70%), and one-third used Spanish as their preferred language. One hundred fifty of 175 lung zones (85%) were interpretable, with expert agreement of 87% and a kappa of 0.49. 98% of subjects reported that they could perform this LUS self-exam at home. Conclusions This pilot study reports that training HF patients to perform a LUS self-exam is feasible, with reported high selfefficacy. This supports further investigation into a telemedicine model using LUS to reduce emergency department visits and hospitalizations associated with HF.

Prioritizing trainee safety during the COVID‐19 era is paramount. In March 2020, the AAMC recommended prohibiting medical students from direct patient care in significantly affected regions. Guidelines continue evolving; however, the AMA continues to recommend clinical experiences, not requiring direct patient care, be achieved through virtual formats.
